NVLINK / SLI WORTH IT OR NOT??

[Ayush007]

Hello guys,

 

I hope you all are doing well

(Your opinion is highly valuable 4 me)

 

I know many of you have depth knowledge regarding gpu ,so I thought to share diz post wid u.

 

I have two rtx 2080 ti HOF edition n linked them through NV LINK , Monitor-3k WQHD monitor(21:9).

 

(NOTE- REGARDING BELOW STATEMENT IM NOT SURE, AS IM LITERARY CONFUSE B/W NVLINK /SLI)

 

I have assume tht current gen game don’t support sli due to old technology, I hope thts why Nvidia reveal NV LINK in  rtx series , so tht multiple gpu technology survive in current gen game. Is it true.Im literary confuse between nvlink or sli.

please rectify me if I’m wrong??

 

Your cordially

Test the performance. Take one card out and retest. Decide if the difference is worth selling the card for as much as you can get for it.

[Envit0]

^^ This. If you already have two GPU's test the games you play with single, with SLI and compare the two...  

[Levent]

You got 2 RTX2080s and asking us if SLI is worth it?

If you do have it, you really should think before buying stuff.

[Alex Ushigome]

CPU? What games? What monitor? All these variables are importent as there may be bottlenecks worth improving instead of SLI, or  games that aren't optimised for it, or you may be like me, where SLI is near 100% scaling and highly needed.

[jones177]

I have two 2080 tis as well but now they are in different computers. At some point after nex gen comes out they may be used in SLI. That will depend if I am playing any SLI games. 

Right now I am tempted to get a third 2080 ti because the game I am playing now supports it. What stops me is the hassel my GTX 1080 ti SLI rig became on some games. It is the main reason I got a second 2080 ti.    

 

The best thing you can do with two 2080 ti is have one connected to a TV and one to a gaming rig. That is what I do now.

Hahahahaha 

 

quite funny , good sense of humour.

I will keep it in my mind before buying any product in future.

Please understand you're the anomaly that simply has more money or the desire to spend it than most. 

 

2080Ti's for over $1000 each are not something you just "pick up" for 99% of people, and throw one on a TV based system.

 

SLI is in no way worth it for the return on investment at all, and the proper answer to the OP's question is a resounding NO, not speculation on spending more money for something that we all know isn't worth it.

I assume the monitor is 120hz? I haven't played on a 21:9 in ages, but I'm pretty sure my 2080 Ti could handle a 120hz easily, since I'm playing at 2160p120. It really depends on if the games you play like SLI, and your financial situation. Having SLI wouldn't hurt (providing they are watercooled/getting enough air), but it probably wouldn't help much either.

[Mick Naughty]

Worth it to me but I simply can’t afford it anymore. 

I would have gone with a pair of 2080’s though. More affordable and should be able to get decent frames at 1440 and a cpu should be able to keep up as fancy as the amd stuff is supped to be. 

But all of my games support sli so I don’t have to worry about that kinda stuff.

I am communicating to another anomaly.

 

None of it is an investment unless you make money with them and I did that from 1987 to 2018.  

I retired from making money with my computers last year but I made sure that I would have enough income to buy high end computer parts for the foreseeable future.

 

Paying off my mortgage helped as well since it was a lot more than a 2080 ti a month.

'worth it' is up to you, but I think a more relevant question you can ask yourself is "can I make use of it in any modern games?"

 

SLI support at launch has never been common, and for many years people have claimed that SLI is dying/dead because of this, but regardless of what those people preach at the end of the day all that matters is if support for games that you want to play exists or will exist. 

 

If you google search for games with SLI support you can find lists that various sites have complied, and some are updated as SLI support is sorted out by the community or Nvidia themselves.Remember that game developers are NOT the ones who create/add SLI profiles into Nvidias driver packages - Nvidia themselves are the ones who do that.What developers can do is code their graphics engines in ways which will play nicely with SLI so that well-performing SLI profiles can be created.

 

One last bit of consideration for you is that for a reason I have not yet studied, DirectX 12 doesn't seem to have any capacity to allow the old SLI method to work at all, so at least for the time being your games will need to run in DX11 mode to even be able to try sorting out an SLI profile.

[vong]

I think 1 gpu is enough for 3440x1440p. I still have a 1080 ti with a 3440x1440p monitor and it runs AAA games at high/ultra settings just fine.

[RecyclopsReveng3]

SLi is tricky these days. If you're using your PC as a workstation as well it might be worth it. If you're only gaming, it's not worth the price:performance. I mean, if you already own the card and you don't NEED the money, then maybe in the future games will be more optimized for SLi but it's just not really worth it. A friend of mine is running 2080 Ti's in SLi simply because he's a hardcore enthusiast and he has money to burn. But performance wise, he only see's around 5-15% (max) performance boost from running 2. I think we're going to see a big bump in multi-GPU cards in the future. It's been a while since nvidia release an X2 card, they're about due and with AMD starting to perform really well at a good price, nvidia needs to do something special.

Dear Kalm_Traveler1,

 

Thnx for taking interest in my section.

I appreciate it

 

I have a great confusion,

please help me if you can, Actually I have just assume tht I  hv used nvlink instead of sli.!!

now does it change the scenario or not???

 

Please rectify me if I’m wrong!!!!!

 

 

your cordially

Well you don’t have a choice really. The interface is called nvlink. Though on the mobo it will be called sli for now. 

Dont think too much about it, in this term it’s the same.

For your co-operation , I really mean it

Yea you are actually ri8, 

I should not overthink.

Nvlink and SLi are the same thing. Sorry, I'm old, I still refer to it as SLi. The problem is that games these days aren't really optimized or supporting NVLINK/SLI and honestly NVIDIA themselves aren't really supporting it a whole lot themselves. At the end of the day, yes, technically, there is a performance boost, is it a big boost? No absolutely not. But if you have the cards already, you might as well use them. Liquid cool them, make a show-grade PC out of it.

It's just a confusion caused by Nvidia and motherboard manufacturers. 

SLI = scalable link interface (Nvidia's acronym - not the original 3dfx scan line interleave) is both a technology and a physical connector.

NVLink is also both a technology and a physical connector.

 

Prior to the Quadro GP100 / Volta graphics cards (Tesla V100, Quadro GV100, Titan V, etc), Nvidia used the SLI connector as  way to link up several of their graphics cards together both for consumers for gaming, and for professionals for pooling processing power and VRAM. From the Quadro GP100 and onward, they developed a newer, faster technology for linking multiple cards and called it NVLink - along with a new physical connection.

 

Although the NVLink connector is now used on consumer graphics cards, the technology side of it being used is still SLI - so if you really want to be technically accurate what we are using for gaming is "SLI over NVLink". Thus, for us the scenario is still exactly the same as if using older cards with SLI connectors.

It's been a while since nvidia release an X2 card, they're about due and with AMD starting to perform really well at a good price, nvidia needs to do something special. 

If your friend has SLI working properly and is only seeing a 5-15% performance increase, that seems very likely to be a CPU bottleneck - not an SLI shortcoming.

 

Assuming that your overall game performance is being limited by graphics processing capacity, say max settings at a high resolution (1440p+ minimum) and NOT by the CPU, and that you are running a game that can play well with SLI enabled, your friend should be seeing more like 50%-90% increase by using 2 cards over 1. If he is only seeing 5-15% (but the games are indeed running fine) that would make me think he's just hitting a CPU bottleneck (CPU can't kick out enough frames to adequately make use of the available graphics processing capacity of 2 cards working together).

 

I would be less surprised if most of his games just won't use the 2nd card at all, or won't run with a custom SLI profile being forced.

Dear Kalm_Traveler1,

 

Very nice explanation,

Now I can see things clearly 

 

You have quite depth knowledge about PC stuffs n technology

 

I appreciate it

Bdw should I buy rtx Titan , by selling  both of them ?!!
